How To Measure 

  • Wrap a strip of paper around your finger.

  • Mark the spot on the paper that feels like a good fit.

  • Lay the paper out flat and measure it with a ruler

  • Look for the measurement on the Northern Royal Conversion chart for your size. 

Here Are some Simple Tips When It Comes To Measuring Your Finger 

  • It is best to measure your finger when you feel your body is at a normal temperature. This means do not measure your finger when you are experiencing chills or if you feel your body is warm.
  • Take several measurements during different times of the day when you feel your body is at a normal temperature.
